Dwyer Series DHII Digihelic II Differential Pressure Controller DHII-002,
The Series DHII Digihelic® II Differential Pressure Controller takes all the features
of the standard Digihelic® Pressure Controller and packages them in a robust NEMA
4 (IP66) housing.
The Digihelic® II Pressure Controller combines the 2 SPDT control relays, 4 to 20 mA
process output and Modbus® communications with a large, brightly backlit 4 digit LCD
display that can easily be seen from long distances. The electrical wiring has also been
enhanced in the DHII with its detachable terminal blocks. The removable terminals
allow the install to easily wire the terminal block outside the housing and then attach
to the circuit board, reducing wiring difficulties and installation time on the process.
